Vauxhall Vivaro Antipollution Light Diagnosis

What Does the Antipollution Warning Mean?

The antipollution system in a Vivaro is made up of multiple components that work together to reduce harmful emissions. These include:

• EGR valve (Exhaust Gas Recirculation)
• DPF (Diesel Particulate Filter)
• O2 and NOx sensors
• ECU software and fuelling maps
• Injectors and air/fuel ratio controls

If any of these systems begin to behave outside expected parameters, or if a module is replaced or misconfigured, the antipollution warning will generally display.

Common Vivaro Faults That Trigger This Light

For Vauxhall Vivaro vans, common triggers include:

• EGR valve issues: clogged or malfunctioning valves are especially common on 1.9 and 2.0 diesels
• Blocked or failing DPF: particularly on short-run vans or those used primarily around town
• NOx or O2 sensor faults: worn sensors misreporting emissions levels
• Injector imbalance: can cause over-fuelling or soot build-up
• Software or ECU mismatch: often occurs after module replacement or cloning
• Low-quality fuel or contamination

We use specialist diagnostics geared specifically to the Vivaro to interpret live sensor data and module communication errors.
